It seems this should be straightforward, but every approach I attempt in an effort to locate detailed entries from Norwegian real estate books fails. For example, an entry on the right-hand page linked below shows a pantebok reference of No. 3, Fol. 250. I want to locate that detailed entry (3-250). ​*Permanent pagelink:* http://www.arkivverket.no/URN:tl_read?idx_id=17507&uid=ny&idx_side=-83​ The page has an orange button that says (in English) "Search for mortgage book". My first thought was that I click that button and then select the correct entry from the list of mortgage books that it provides. However, the date ranges of those books does not include 1851, which is the year of the entry I am searching for. Backing up to the main search page, when I attempt to search manually, I don't seem to be searching for the right thing - or at least I'm not finding what I expect! Would someone please explain to me how to use the reference number from the register to locate the detailed entry? Or am I fundamentally misunderstanding something? Thanks! -- James Aylard
